fix(idaa): require JWT for all Novi users, remove embed meeting button

- Issue JWT to all verified Novi users, not just moderators; unauthenticated
  URL access no longer sufficient to join an IDAA video conference
- Remove 'embedmeeting' from Jitsi toolbar via explicit toolbarButtons whitelist;
  the embed dialog exposed the Jitsi host/room URL violating IDAA privacy rules
